【问题解决】安装Scrapy失败解决Failed building wheel for twisted-iocpsupport

错误显示如下

Building wheels for collected packages: twisted-iocpsupport
  Building wheel for twisted-iocpsupport (pyproject.toml): started
  Building wheel for twisted-iocpsupport (pyproject.toml): finished with status 'error'
Failed to build twisted-iocpsupport

  error: subprocess-exited-with-error
  
  Building wheel for twisted-iocpsupport (pyproject.toml) did not run successfully.

  [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for twisted-iocpsupport
ERROR: Could not build wheels for twisted-iocpsupport, which is required to install pyproject.toml-based projects

关键的是这句话：

building ‘twisted_iocpsupport.iocpsupport’ extension
error: Microsoft Visual C++ 14.0 or greater is required. Get it with “Microsoft C++ Build Tools”: https://visualstudio.microsoft.com/visual-cpp-build-tools/

说明需要安装Microsoft Visual C++14.0或更高版本
（原本以为错误原因是Failed building wheel for twisted-iocpsupport…）
